Answer:
0.0567 N
Explanation:
q1 = 3 micro coulomb
q2 = - 2 micro coulomb
OB = 50 cm
AB = 60 cm
By using Pythagoras theorem in triangle OAB


OA = 78.1 cm
By using the Coulomb's law, the force on 3 micro coulomb due to -2 micro coulomb is

F = 0.0885 N
The horizontal component of force is
= F CosФ = 
= 0.0885 x 50 / 78.1 = 0.0567 N
Answer:
I think it could be 85 m/s East but go for what you thought of because im not exactly sure.
Explanation:
C, They change their shapes depending on their containers
Positive - Friction allows us to create heat in a desperate situation, like being lost in the woods. If we didn't have friction, we would probably freeze to death.
Negative - Friction can also cause unwanted fires, such as forest fires. If friction didn't exist, we wouldn't have these.
Answer:
The correct choice is A. Yes, the more exercise the better.
